I had these installed briefly in my SX, but I have since bought a new bass so I no longer need these. These are great pickups for a late '60s or '70s Fender Jazz Bass as they nail that tone IMO. I was looking for the pre-CBS tone, and while these pickups can do that, it is not they're strength. BassPlayer awarded them their Top Tone and Recording awards in the famous shootout. Here's the specific description for those who are interested: http://www.aeroinstrument.com/bp_jb4_shootout_p_3.html These go for $180 new, so I am asking $140. The pickups are only a month or so old, and have no cosmetic damage aside from the factory relic'ed look. SOLD Thanks!
